The cumulative distributive function (CDF) Fx(3) is 0.61.
The cumulative distributive function (CDF) of a random variable X is the probability that X takes a value less than or equal to x. In this case, we are asked to find Fx(3).
Since the random variable X is given with a probability mass function, we can calculate the CDF by summing the probabilities of X being less than or equal to 3. This can be expressed as: [tex]Fx(3) = P(X<=3).[/tex]
For X = 0, P(X<=3) = 0.23.
For X = 1, P(X<=3) = 0.23 + 0.13 = 0.36.
For X = 2, P(X<=3) = 0.23 + 0.13 + 0.10 = 0.46.
For X = 3, P(X<=3) = 0.23 + 0.13 + 0.10 + 0.15 = 0.61.
Therefore, the cumulative distributive function (CDF) Fx(3) is 0.61.

Use substitution to solve -4x + y = 3, 5x - 2y = -9
Using the substitution method, the solution of the system of equations -4x + y = 3 and 5x - 2y = -9 is (x, y) = (1, 7)
We can solve this system of equations using the substitution method by solving for one variable in terms of the other in one equation, and then substituting that expression into the other equation. Here's how:
-4x + y = 3 (Equation 1)
5x - 2y = -9 (Equation 2)
Solving Equation 1 for y, we get:
y = 4x + 3
Now, we substitute this expression for y into Equation 2 and solve for x:
5x - 2(4x + 3) = -9
5x - 8x - 6 = -9
-3x = -3
x = 1
We have found the value of x to be 1. Now, we substitute this value back into Equation 1 to find the value of y:
-4(1) + y = 3
y = 7
Therefore, the solution to the system of equations is (x, y) = (1, 7)

The cost price of 20 articles is the same as sellling price of 16 articles find the gain percent
If the cost price of 20 articles is the same as selling price of 16 articles, then the gain percentage is 25%
To find the gain percent, we first need to calculate the profit earned on the sale of the 16 articles.
Let the cost price of each article be "C" and the selling price of each article be "S".
Given that the cost price of 20 articles is the same as the selling price of 16 articles, we can write:
20C = 16S
We can simplify this equation to:
S = (20/16)C = (5/4)C
Now, let's calculate the profit earned on the sale of 16 articles:
Profit = Total Selling Price - Total Cost Price
Profit = 16S - 20C
Profit = 16(5/4)C - 20C
Profit = 5C/2
The profit earned is 5C/2. The profit percent can be calculated as:
Profit Percent = (Profit / Cost Price) x 100
Profit Percent = (5C/2) / (20C) x 100
Profit Percent = 25%

h(x)= -x + 5, solve for x when h(x) = 3
According to the given information, the solution to H(x) = 3 is x = 2.
What is equation?
In mathematics, an equation is a statement that asserts the equality of two expressions. An equation typically consists of two parts: the left-hand side (LHS) and the right-hand side (RHS). The LHS and RHS are separated by an equals sign (=), indicating that they have the same value. The general form of an equation is: LHS = RHS
To solve for x when H(x) = 3, we substitute 3 for H(x) in the equation and solve for x:
H(x) = -x + 5
3 = -x + 5
Subtracting 5 from both sides, we get:
-2 = -x
Multiplying both sides by -1, we get:
2 = x

b. Interpret the slope and the y-intercept.
Months, Hair

Length, y
11.0
12.5
14.0
Answer:
a. To write a linear function that relates the length of hair to the number of months, we need to find the slope and y-intercept of the line that passes through the given points. We can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.
Using the given data, we can find the slope as:
m = (y2 - y1) / (x2 - x1) = (14.0 - 11.0) / (6 - 0) = 0.5
And we can find the y-intercept as:
b = y - mx = 11.0 - 0.5(0) = 11.0
So, the linear function that relates the length of hair to the number of months is:
y = 0.5x + 11.0
We can also graph this function as a straight line, passing through the given points (0, 11.0), (3, 12.5) and (6, 14.0), as shown below:
linear function graph
b. The slope of the function is 0.5, which means that the length of hair increases by 0.5 inches every month. In other words, the slope represents the rate of change of hair length with respect to time.
The y-intercept of the function is 11.0, which means that if the person doesn't cut their hair at all (i.e., x = 0), their hair length would still be 11.0 inches. In other words, the y-intercept represents the starting value of the hair length.

The cost of each store in two months is: Store A is 4281, Store B is 5485, Store C is 3153, and Store D is 6413.
To calculate the total number of pets delivered over the period of 2 months to each store, we need to add the corresponding elements of matrix K and matrix L. The result will be a new matrix representing the total number of pets delivered to each store.
So, we have: Matrix K:

Total pets delivered to each store:
| 9 7 5 |
| 10 5 12 |
| 3 9 5 |

To calculate the cost of each store in two months, we need to multiply the total number of pets delivered to each store by the price of each type of drink, as given by the matrix:
| 225 195 212 |
So, the cost of each store in two months is:
Store A: (9 × 225) + (7 × 195) + (5 × 212) = 4281
Store B: (10 × 225) + (5 × 195) + (12 × 212) = 5485
Store C: (3 × 225) + (9 × 195) + (5 × 212) = 3153

Let X >0 denote a random variable with p.d.f. fx(2) and c.d.f. Fx (I). Assume Fx() is monotone increasing, and let Y = FX(X). That is, Y is a random variable that takes the value Fx (1) when X = r. Find fy(y). Mark the correct answer (a) fy(y) = 1,0
The probability density function (PDF) of Y can be determined by the transformation of the PDF of X. Using the transformation rule, we can calculate that fy(y) = fx(x) |dx/dy|, where x is a function of y, since y = Fx(x).
We can use the Chain Rule to determine the derivative of x with respect to y. Since Fx is a monotone increasing function, dx/dy = 1/F'x(x). Substituting this into the transformation rule, fy(y) = fx(x) / F'x(x).
Therefore, to find fy(y), we need to calculate F'x(x). Fx is the cumulative distribution function, which means that its derivative F'x(x) is the probability density function of X, or fx(x). Substituting this into the transformation rule, fy(y) = fx(x) / fx(x). Since fx(x) = fx(2) and fx(2) is a constant, fy(y) = 1/fx(2).
To summarize, the probability density function of Y is given by fy(y) = 1/fx(2).

2. In 2017, Aspinwall Company issued $200,000 of bonds for $175,000. If the face rate of interest was 9% and the effective rate of interest was 7.99%, how would Aspinwall calculate the interest expense for the first year on the bonds using the effective interest method?
a. $175,000 × 7.99%
b. $175,000 × 9%
c. $10,000 × 7.99%
d. $10,000 × 9%
3.
Use the information below for Focal Point Corp. for 2017 and 2018 to answer the following question:
Retained earnings, December 31, 2017 $300,000
Retained earnings, December 31, 2018 345,000
Dividends payable, December 31, 2017 19,000
Dividends payable, December 31, 2018 29,000
Net income—2018 150,000
Assume that there were no retained earnings transactions other than those dealing with dividends and net income. How much dividends did Focal Point declare during 2018?
a. $95,000
b. $105,000
c. $140,000
d. $150,000
1) Option a. Depreciation expenses of $6,710 will be recorded each year. is correct.
2) Option c. 175,000 × 7.99% is correct
3) Option b. $105,000 is correct.
1) The annual payments of $10,000 and the recorded cost of the asset of $67,100 are used to calculate the annual depreciation expense using the straight-line method.
Depreciation expense = (Recorded cost of the asset - Residual value) / Useful life
= ($67,100 - $0) / 10 years
= $6,710 per year.
2) The effective interest method calculates interest expense by multiplying the carrying value of the bond (i.e., the amount at which it was issued minus any discount or plus any premium) by the effective interest rate (i.e., the rate that discounts the bond's future cash flows to the carrying value).
Therefore, the interest expense for the first year on the bonds would be $175,000 × 7.99% = $13,965.
3) The dividends declared during the year can be calculated as follows:
Dividends declared = Net income - Increase in retained earnings - Decrease in dividends payable
= $150,000 - ($345,000 - $300,000) - ($29,000 - $19,000)
= $105,000.

The volume of two similar figures are given. The surface area of the larger figure is given. Find the surface area of the smaller figure.
V=4000m^3
V=6912m^3
S.A.=2304m^3
Te surface area of the smaller figure based on the ratio is 1600m²
Calculating the surface area of the smaller figure.The ratio of the volumes of two similar figures is equal to the cube of the ratio of their corresponding sides.
Let x be the scale factor between the smaller and larger figures.
Then we have:
(x³)/(4000) = 6912
x³ = 6912/4000
x³ = 1.728
Taking the cube root of both sides, we get:
x = 1.2
So the scale factor from the larger figure to the smaller figure is 1:1.2.
The surface area of a similar figure is proportional to the square of the scale factor.
So we can use the scale factor to find the ratio of the surface areas:
SA(smaller) / SA(larger) = 1/(1.2)²
We know that the surface area of the larger figure is 2304m^2, so we can solve for the surface area of the smaller figure:
SA(smaller) = 2304 * 1/(1.2)²
SA(smaller) = 1600m²
Therefore, the surface area of the smaller figure is 1600m²

Answer:
[tex]\boxed{x=0}[/tex]
Step-by-step explanation:
We need solve for x
[tex]3=x+3-5x[/tex]
substract 3 to both sides of the equation:
[tex]3-3=x+3-5x-3\\0=-4x[/tex]
divide both sides of the equation by -4
[tex]\frac{0}{-4}=\frac{-4x}{-4}\\0=x\\\equiv x=0[/tex]
